Yes, so I might try my hand at a 3 speed hub when this one blows up.... Otherwise it's back to a casette, and replacing chains and gears every so often. I guess what we really need is an internal transmission that goes with the motor setup. I think 4 gears is all you really need at this power level ...

I was planning to install a 40a BBSHD on my 9-speed derailleur style FS fatbike but it seems that only the triangle packs from Luna support more than 30a continuous draw and that bike has a pair of Sharks with 30a BMS's. That means I'll soon be running 40a through my SA 5-speed at 52v..... I'm runn...

It's exciting but still un-proven. I'd like to discuss the changes that have been made with the newest 5-speed compared to the previous model. I can't find much on the previous model though. even 3 speed beats the hell out of 1 gear for torque starved ICE motors especially on motorized bikes, mostl...

I just purchased an Sturmey IGH RX-RK5 for my bike, however I'm having trouble with the chain slipping on the front kog. What kind of kog do you use on the front? I know the RX-RK5 uses thicker chain, because we could not use 9-Speed bike chain on it. However, the new chain we're using keeps slippi...

I ended up just going without a tensioner or derailleur. It's a 1600 watt cyclone kit basically, and 44t chainwheel up front. WP_20161104_17_38_55_Pro.jpg How much wattage are you running through that 5-Speed? Also love to see more about your build, do you have a build post? Sounds like lots of fun...

After reading the Sturmey Manual here: http://www.sturmey-archer.com/files/catalog/files/85/MANUAL%20-%205%20SPEED%20ROTARY%20HUBS.pdf I can see there have been some mistakes when installing it. It says in the manual Step 4: ) "If the bicycle has reversed or standard rear fork ends, rotate the shift...

Another question though. How are you supposed to shift these Internally Geared Hubs? I never shift under motor load, but I heard somewhere that they only actually shift gears when the hub is off-loaded. Before I had an internally geared hub, I had a standard 9 speed cassette, and I'd shift it but le...

Nice .... I note that the specifications sheet list 3/32 cogs. Might one of those resolve your problems ? Reference: http://www.sturmey-archer.com/en/products/detail/rx-rk5 http://www.sturmey-archer.com/files/catalog/files/85/SPECIFICATIONS%20-%20IGH%20C50.pdf I'm using the cog it came with... and ...

LewTwo wrote:THe OP did not tell what IGH he is using. There are 3/32 cogs available for SA. I am running a 3/32 chain on my SA 3 speed hub without any tensioner but I did have to get a half-link chain in order to adjust the proper length.

Harold, I've been following this discussion and even though you don't think the slippage is at the back I have to believe that that is where the problem originates, and then maybe causes a skip on the front chain ring. My best guess is that something is wrong at the derailleur tensioner. An easy ch...

That shouldn’t be happening. Here are some things to check: Was everything fine before you have installer the hub? Could the chainring or chain be worn? Did you shorten the chain? Are you sure that the slippage is at the chainring and not at the rear cog or inside the hub? Avner. Everything was fin...

I just watched this video here demonstrating the compatibility of 3/32'' and 1/8'' chain on single speed chain rings. Obviously the 3/32 doesn't fit, which is strange considering how many people online say that 1/8 chain is interchangeable.. There are 3/32" and 1/8" chains, and there are 3/32" and ...

Check for tight/ seized/ stiff links in the chain and maybe lube it a little.
Also look for wear on the sprocket teeth.

I have a new Internally Geared Hub with 1/8" kog and my front chain ring is 3/32 for multi-speed use. I've tightened the chain tension with the old derailleur but the chain still slips when I put moderate pressure on the peddles. I've read that the 1/8" chain works fine with 3/32 chain-rings, and th...

I'm Looking for a Single speed chain ring specifically compatible with 1/8'' chain. Has to be 104mm bcd and 36-42 tooth. Everytime I look online for it I get chain rings compatible with multi speed chain. As evidenced by this video: SeO9bvQ-Ut0 A real single speed chain ring will not fit multi-speed...

So it's getting to be about that time where i will be needing new gears. Is there a place I can order from directly besides aft or the chinese supplier? The chinese company is kind of difficult to get a hold of and AFT is kinda far away and expensive.
